India’s GSLV rocket successfully launches military communications satellite
India today successfully launched a military communications satellite using the Mark II version of its large GSLV rocket, the rocket’s fourth successful launch in a row.
Using a combination of liquid and solid-fuelled stages, the GSLV was designed to place communications satellites into geosynchronous transfer orbits. To this end, GSLV has increased performance over the smaller Polar Satellite Launch Vehicle (PSLV), from which it is derived.
GSLV’s first stage consists of a solid-fuelled core, with four radially-mounted liquid-fuelled strap-ons. The strap-ons are part of the first stage, and do not separate from the core. GSLV’s second stage, which is closely related to PSLV’s second stage, burns hypergolic liquid propellants, while the rocket’s third stage uses cryogenic fuel.
…The Mark II, which has a stretched third stage with an Indian engine, first flew in April 2010 but its new engine failed to ignite. The first successful Mk.II launch took place in January 2014. India also has a GSLV Mk.III. However, this is a completely new rocket that reached orbit for the first time last year. Excluding the Mk.III, Thursday’s launch was GSLV’s twelfth flight. In its previous eleven launches, GSLV has recorded six successes, four failures and one partial failure….GSLV’s current run of four consecutive successful launches is the longest that the rocket has achieved.
The leaders in the 2018 launch standings:
8 China
5 SpaceX
3 Japan
3 ULA
3 Russia
2 Europe
2 India
Both Russia and China have scheduled launches for today, with SpaceX having a launch scheduled for tomorrow, so expect these standings to be updated a lot in the next 24 hours.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
